Please be simultaneously referring to figs. 1 to Fig. 3, in the present embodiment, the carrying curved surface W1 of heat radiation lobe 112 is the curve with a point of inflexion A1 on plane P 1.Say further; In the lighting device 100 of Fig. 1; The part that the carrying curved surface W1 of heat radiation lobe 112 is covered by optical element 160 cover is essentially the part of a sphere, that is in Fig. 3, carries curved surface W1 and is projected in that formed camber line has the subtended angle θ 1 greater than 90 degree on the plane P 1.In the present embodiment, subtended angle θ 1 is for spending less than 125 greater than 90 degree.Therefore, above-mentioned flexible circuit board 120 also is a curved surface along carrying curved surface W1 configuration.
Therefore; The orthographic projection of heat radiation lobe 112 on central shaft C1 is a line segment; And orthographic projection is positioned at two light-emitting component 130A, the 130B of the opposite two ends of central shaft C1, and its emergent light vector L1, L2 orthographic projection vector L1a, the L2a on central shaft C1 is in the opposite direction each other.Hence one can see that, and the light-emitting component 130 of present embodiment just can be arranged between the scope of above-mentioned two light-emitting component 130A, 130B, that is the light-emitting component 130 of Fig. 3 is able to cross over the point of inflexion A1 that carries curved surface W1 through flexible circuit board 120 and is configured.In view of the above; Light-emitting component 130 just can increase it along the appearance profile that carries curved surface W1 and go out optical range; And let its rising angle greater than 90 degree, promptly be able to overcome the restriction of its rising angle as the lighting device 100 of light source, and make it meet the illumination zone of existing incandescent lamp bulb with light emitting diode.
Please again with reference to figure 3; In the present embodiment, radiating piece 110 is divided into a top H1 and a neck N1 according to its profile, wherein it should be noted that; Light-emitting component 130 all is positioned at the top H1 of radiating piece 110; And the minimum outer diameter of top H1 is in fact greater than the maximum outside diameter of neck N1, that is table skeleton in addition, and neck N1 can't be greater than top H1.Thus, this measure can guarantee that just light L2 that light-emitting component 130B for example sent can be because of the excessive crested of neck N1, and thereby reduces the luminous efficiency of lighting device 100.
In addition, Fig. 4 is the distribution curve flux figure of the lighting device of Fig. 3.Fig. 5 is the distribution curve flux figure of existing incandescent lamp bulb A19 type, wherein the incandescent lamp bulb of the lighting device of Fig. 4 and Fig. 5 all with identical configuration kenel (being state as shown in Figure 3) so that contrast its luminous situation.Please be simultaneously with reference to figure 3, Fig. 4 and map 5; In the lighting device 100 of Fig. 3; Light-emitting component 130 is equidistantly arranged along the carrying curved surface W1 of heat radiation lobe 112 each other, and the distribution curve flux figure that it produced can be near the luminosity and the scope of incandescent lamp bulb A19 type.So the designer can adjust the configuration mode of light-emitting component 130 to this, just can let lighting device 100 meet the luminescent condition of incandescent lamp bulb A19 type.
Fig. 6 is the side view of a kind of lighting device of another embodiment of the utility model.Please refer to Fig. 6, in lighting device 200, the spacing of light-emitting component 130 between a plurality of orthographic projections on the central shaft C1 can change along central shaft C1.In other words, light-emitting component 130 in the present embodiment, the density degree of its arrangement can thickly be arranged by dredging extremely towards lamp socket 140 from optical element 160, so that lighting device 200 is in use, it can strengthen the brightness towards lamp socket 140 places.Say further, for letting lighting device 200 reach required distribution curve flux, the spacing of light-emitting component 130 between a plurality of orthographic projections on the central shaft C1, it can increase progressively, successively decrease along central shaft C1, or comprises this two kinds of arrangement modes simultaneously.In other words, present embodiment does not limit the layout of light-emitting component 130 on flexible circuit board 120 and heat radiation lobe 112, and the designer can suitably change according to user demand, with the distribution curve flux of adjustment institute desire formation.
Similarly, also do not limit the appearance profile of heat radiation lobe 112 in the above-described embodiments.Through the deflection characteristic of flexible circuit board 120, the designer can be according to lighting demand the profile of change heat radiation lobe 112, to adjust the illumination zone of lighting device 100 by this.In other words, at the utility model among another embodiment that does not illustrate, the carrying curved profile of heat radiation lobe can be the curved surface that comprises a plurality of points of inflexion, with by this as the means of adjusting luminosity and scope.
In addition, user's light illumination mode that also can pass through control circuit (or microprocessor etc., do not illustrate at this) illumination apparatus 200 is controlled further.Following is that example is carried out the drive pattern that bright subregion is lighted with Fig. 6.
Lighting device 200 with Fig. 6 is divided into A, B two districts that are configuration up and down along central shaft C1 in the present embodiment, and makes A, each district of B have independently light and shade and luminous intensity through above-mentioned control circuit.For instance, when the user needed the local light source of specific direction, the light-emitting component 130 that just can control A district or B district by this produced complete dark or complete bright effect, also can control its luminosity further.
